Bryn y Fan 482m P175 (1581ft) Welsh Marilyn

Geological overview Just south of Stourport a magnificent river cliff of fine grained red sandstone is seen. Although mainly homogenous in terms of geology, there are white streaks and thin bands of coarse material running throughout the section. The soft sandstone of Redstone Rock is easily carved and there is evidence of human-made habitation in the cliff face since Stone Age times. The caves that can be seen today were mostly made in the 12th century, when a hermitage was established there, conveniently located for the hermits to be on hand to offer blessings and prayers for passers-by in return for alms. It was said to house up to 500 men, who may have also manned the ferry crossing, which was there due to the presence of a ford until the river was dredged. The caves were later used as domestic dwellings and were inhabited almost continuously until the mid twentieth century. Source: Geopark.org

This area of the Wyre Forest Site of Special Scientific Interest belongs to John Ruskin's charity, the Guild of St George and is managed by the Wyre Community Land Trust. We are managing this area to support a mixture of high forest and heathland, which are valuable habitats for bats, birds and other species. In large areas of the woodland, the trees. are relatively young, and mainly comprise oak with bracken and bramble. This lack of diversity is a result of changes in woodland management following World War 1. when much of the woodland was no longer coppiced because of a collapse in the charcoal industry. In order to improve the habitat diversity, some trees have been removed to give those remaining more space to grow into large mature trees. The trees that are felled are extracted and processed at the Wyre Community land Trust's woodyard and sawmill at St George's Farm and used to make a variety of timber products and firewood. Volunteers have helped plant trees to ensure the forest has a diverse mixture of tree species that is more resilient to pests, disease and the effects of climate change.

Bryn y Fan is a prominent summit in mid Wales standing at 482m above the Llyn Clywedog reservoir. There is a nice trig point and great views. It's a bit of an outlier and you're unlikely to see many people on your walk.

The cutting is through beds of Highley Sandstone. They were deposited in the river channels on swampy deltas 310 million years ago. Their characteristic grey-green tinge indicates deposition in oxygen-poor conditions of a humid swamp. This is in contrast to the red Alveley Sandstone, seen earlier, formed in the oxygen-rich environment of a semi-arid desert. The pronounced 'bedding planes' running almost horizontally across the rock face, represent breaks in deposition. 'Cross-bedded' or 'current-bedded' layers are inclined at angles to each other. This cross cutting relationship is a result of changing directions in the river current that deposited the sediments, in the same way as changes in wind direction caused the dune-bedding seen in the Bridgnorth Sandstone

This is the viewpoint up the hill to the east of Dylife. the best view is north down the Afon Twymyn valley.

What he said ^^^^^^^

Just south of Stourport-on-Severn, Redstone Caves are made from Triassic sandstone. Carved out in the 12th century and then home to a hermitage, it seems extraordinary today that once up to 500 men lived here. The Geopark Way, a long-distance footpath specialising in geological marvels in the area, runs unsurprisingly right past these caves.
